Data by sellers are automatically suspect. I refer only to independent tests by knowledgeable end-users, ideally addressing the advice in terms of design and measurable output over a specific brand.

Now, to be fair, that usually ends up with a short list of brands unless you go custom built (which some do or have done for various projects, myself included).

Anyway, all I'm really advocating here is for making decisions based on data over brand name; interpreting whatever data is available is something inherently fallible, even in dealing with assembly line automobiles, but ignoring that data entirely means you have only crossed fingers and dubious testimonials to go on.

I know this post is ancient, but it is one of the most detailed, thoughtfully-written, and informed explanations about dampers that I have ever encountered. From a chassis design engineer, I thank you [Fishey] for your contribution!
